摘　　要：关于带有纵向内筋的薄壁筒形件强旋成形时金属流动规律和变形机理,可以通过实验获得.实验主要涉及所用的旋压方式,所需的旋压设备,旋压工装的设计,旋压管坯的制备,以及部分工艺参数对试件成形性的影响.分析了旋压件产生某些质量缺陷的原因.通过实验获得必要数据,为以后将要进行的人工神经元网络预测和有限元模拟奠定了坚实的基础.The plastic flow law and deformation mechanism of the metal with respect to power spinning deformation of thin - walled cylindrical parts with longitudinal inner ribs can be established through experimental tests, which deal with spinning method used, spinning equipment required , design of spinning tooling , fabrication of spinning perform and the influence of some process parameters on formability of sample parts. The causes for defects in spinned parts are analyzed . With necessary data obtained through tests, a sound foundation is established for subsequent Artificial Neural Network prediction and Finite Element simulation .
